Mange. 
Being in conversation with Professor Spooner one day, on skin 
diseases, he said, ‘‘Tumble them all in a bag, and they principally turn 
out mange.” Of late years I have seen very little of it, in comparison 
with what I saw in my early veterinary experience. Then there 
were whole studs affected, from the introduction of a single animal 
suffering from the disease. All our domestic animals are liable to it, 
as well as those not domesticated; but I believe it is not propagated 
from one species to another, as the acarus, which is the cause, if taken 
from one animal, will not live and breed on an animal of another spe¬ 
cies ; for example, you may have horses affected, and dogs in the same 
building will not contract the disorder, and vice versa. The best 
way to detect the presence of acari is to scrape some of the dandriff 
on to a piece of white paper; let it be still, and in a short time you 
will see the small animals creeping about. The first symptoms are 
staring hair and an oozing of yellow albuminous fluid, and redness 
of the skin in animals of a light colour; we cannot see this in dark 
coloured animals very well. We have true inflammation brought on 
by the continued savage attacks of these mischievous parasites. 
As soon as inflammation is set up they move on to another part of 
the skin, thus spreading over the principal portion of the body. 
The parts that are inflamed form scabs. The principal portion of the 
skin being affected, there is a tendency to thickening of the corium as 
a result, the skin thus losing its pliability. Whatever application we 
use for its cure, we should allow it to remain on for some days, 
so that the ova, as they come to life, may come under its influence. 
In the treatment we must pay attention to the state of the consti¬ 
tution, and a great deal will be done by attention to food. In 
summer natural and artificial grasses ; in winter carrots, good 
corn, &c. Internally give aperients, followed by alteratives and 
tonics. The local applications are various, most veterinarians 
having a recipe of their own. I use oil of tar, sulphur, hydro¬ 
chloric acid, turpentine and oil, in cases of long standing; when 
not of long duration, bichloride of mercury, muriate of ammonia 
and water, are found to answer well. Care should be taken, when a 
case is found out, to separate the patient from the other animals, not 
even using the same brushes, buckets, or harness. In sheep this 
disease is called— 
Scabies Ovis. 
Some kinds of sheep are more susceptible to it than others, as 
those with long coarse wool. The causes are anything that will 
bring them into an unhealthy state, the system then being ready to 
receive infection more easily. Imported sheep are often the subject 
of this disorder. An animal affected will fall away in condition, and 
the wool soon falls off. There is a yellowish-brown secretion seen, 
and then a scab is formed, of a dirty white appearance, with puru¬ 
lent matter underneath. The sheep will often nibble at the affected 
parts, or scratch with the feet, which not unfrequently causes ex¬ 
coriation. The back, loins, and sides, are principally affected. The
